2020 Honda Fit Engine Problems

“On June 10th 2026, my 2020 Honda Fit EX-L with approximately 20,000 miles began misfiring while idle at a light. Error codes started appearing on my dash, no check engine light. Honda of Short Pump diagnosed a cylinder 2 misfire (DTC P0302) caused by a carbon buildup on the intake valves and quoted ~$1200 for valve cleaning. This is the identical failure mode described in Honda Service Bulletin 21-007, whose affected vehicles list includes 2015-2020 Honda Fits, and which Honda covers under warranty extension bulletin 23-042 for 10 years/150,000 miles - but only for 2018-2019 model years. …”

“While driving multiple error lights came on. I took my car in and they said it was carbon build up due to bad gas. They cleaned it and it has been working fine. However, this is an acknowledged problem with the 2018 and 2019 Honda Fit. Honda actually extended the warranty for those years to cover those repairs. My car only had 22156 miles on it. And the error I experienced is the exact error that was reported to happen with the 2018 and 2019 models, however I was told my car was not covered because it's a 2020 model. I feel they should have to cover this error in the 2020 model, as well.”

“Vehicle had entire dash warning lights appear suddenly and had noticed a week prior a vibration/clicking when driving at higher speeds over 50mph. Took to dealer and was told vehicle has had misfires and fuel system was badly dirty and needed an immediate cleaning. Why are the 2020 Fit’s not included in the extended warrant on this as the 2018-2019’s are?”

“Over the summer, vehicle lit up all warning lights. Like many others was informed the system needed deep carbon cleaning. There is a tsb for this problem but Honda corporate said it is regular maintenance and warranty does not cover. I have owned the car since January. If other years are covered, why not the 20?”

“The contact owns a 2020 Honda Fit. The contact stated that after starting the vehicle, the warning lights remained illuminated along with the check engine warning light. The vehicle also experienced misfiring while driving at various speeds. The vehicle was taken to the local dealer who diagnosed that the fuel injectors were faulty and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 9,623.”
